Battery Care
Charging
the Battery
The Precedus comes with a high quality rechargeable NiCd
battery. This battery is not charged and needs to be charged
two to three times to reach full capacity before its first use. A
built-in battery charger will charge the battery when the unit
is connected to external power.
Charge the battery by connecting the Precedus to external
power using either the AC adapter or the cigarette plug.
Leave the unit plugged in for a minimum of eight hours. The
Precedus will automatically stop charging and maintain the
full charge.
Battery
Memory
The battery may lose some of its capacity if the battery is
only partially discharged and then charged again. This loss
of capacity is called the memory effect and can be reversed
by discharging the battery completely before charging it
again. Leave the Precedus on until the battery is completely
discharged and then charge the battery to recondition it. A
special battery charger/reconditioner available for the
Precedus will accomplish this automatically.
Desktop
Charger
A desktop battery charger/reconditioner is available for the
Precedus and will quick-charge the battery in approximately
one hour. The desktop charger has a built-in reconditioner
that will remove the memory effect from your battery.
